WEATHER-BOARDING ATTACHMENT FOR TRY-SQUARES.

SPECIFICATION forming part of Letters Patent No. 349,905, dated September 28, 1886.

Application filed February 10, 1886. Serial No. 191,499. (No model.)

To all whom it may concern.-

Be it known that I, \VILLIAM F. SEAR- GEANT, of Marshall, in the county of Saline and State of Missouri, have invented a new and Improved Combined Try-Square and Scriber, of which the following is a full, clear, and exact description.

The object of my present invention is to provide a cheap, durable, and efficient weather boarding attachment for try-squares; and to this end the invention consists of a doublelegged metallic scriber formed with a means for attachment to the stock of the square and carrying a scribing-point, as will be hereinafter more fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar lettersof reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a trysquare provided with my improved weather-boarding attachment. Fig. 2 is an inverted plan view of the attachment removed from the square. Fig 3 is aplan view of a portion of the square and the attachment, and Fig. 4 is a similar view of a modified construction.

Referring now to the construction illustrated in the drawings, Areprescnts an ordinary form of try-square, and B the weather-boarding attachment or scriber, which is formed with two legs, 0 and D, the leg 0 being parallel with the leg D and projecting downward from a shoulder, a, which projects outward at right angles from near the upper end of the leg D. Just opposite the shoulder a there are formed two ears, I) b, so spaced as to snuglyadmit the stock E of the square A, and in the projecting end of one of the ears b there is a threaded socket arranged to receive a set-screw, F.

From near the lower end of the leg Dthere projects a lug, G, formed with an upwardlyextending pin, a, designed to enter a socket,

d, that is formed in the lower end of the stock E.

In applying the scriber to the stock of a try-square the pin 0 is inserted in the socket cl, and the stock forced between the ears b b to the position shown in Fig. 1,where it is clamped to place by the setscrew F.

The shoulder a is formed with an aperture, 6, and in this aperture there is placed a scribing-point, H, the idea being to have a marker always at hand. It will be understood that in using this attachment the leg 0 is placed over the board to be marked or scribed, the work being made by drawing the scribing-point H along the side edge of the leg D.

In Fig. 4 I show a modified construction wherein the attachment is fixed to the stock by a bolt, F, which passes through the stock, as shown.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t 1. In a combined try-square and scriber, the combination, with atry-square in the stock of which there is formed a recess, (1, of a scriber formed with two legs, one of which is provided with ears I) b and a lug, G, said lug having a pin, 0, that fits within the recess (1, a set-screw, F, being mounted in one of the ears b, substantially as described.

2. The combination, with a try-square, in the stock of which there is formed a recess, d, of a scriber formed with two parallel legs, one of which legs is provided with ears I) b, and a lug, G, having a pin, 0, adapted to fit within the recess d, a set-screw or bolt being mounted in one of the ears I), the device being provided with a means for carrying a scribingpoint, substantially as described.
